[Python-checkins] python/dist/src/Lib sets.py,1.19,1.20

[rhettinger@users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Lib
In directory usw-pr-cvs1:/tmp/cvs-serv8853/lib

Modified Files:
	sets.py 
Log Message:
Removed < <= > >= from the API.  Implemented as comparisons of the 
underlying dictionaries, there were no reasonable use cases (lexicographic
sorting of a list of sets is somewhat esoteric).  Frees the operators
for other uses (such as strict subset and superset comparisons).

Updated documentation and test suite accordingly.
